Author gave the MC negative plot-armor while giving the antagonist plot armor instead. MC was written like an efficiency-focused guy but author makes him intentionally nerf himself and even gave him mental debuff out of nowhere. Gave a president a stroke when he tried to nuke the antagonist. Whitewashed the antagonist to look like a revolutionist trying to go the Lelouch route after he had released criminals and told them they can kill, rob and rape whoever they wanted. When people were sent to stopped the antagonist, they somehow want to avoid killing him and only want to capture him because 'killing is wrong' despite all the atrocities and people he killed???
When the antagonist revealed he has an S-rank monster and hundred thousands other monsters after he has killed hundred thousands people, conquered other countries, threatened humanity, revealed that the lives of everyone is on a deadline, and people asked to nuke him, guess what? Nothing happened and instead people decided to argue for restrictions against the ones trying to clear dungeons to save humanity. Bruh, this isn't like those solo leveling dungeons where people are merely at risk. They literally have a countdown to death that everyone knows but everyone keeps trying to court death. It's hard to take this story seriously.
